Abstract

PURPOSE:To facilitate maintenance by memorizing the content of abnormality when the state of operation of a switch element is abnormal after a fixed time since the command for operation of the switch element is emitted. CONSTITUTION:The commands S1-S4 for operation of a switch element are outputted to an output circuit 2 in response to stage advancing commands inputted to an input circuit 1 according to a programme previously stored in a memory circuit 10. After the time required for operating the switch element passes, the detecting codes D1-D4 of an input circuit 5 and the instruction codes of the output circuit 2 are compared, and the operation of output of the switch element is suspended when discordance is decided while each state signal is stored in a memory circuit 9. When an inspection command R is given to an input circuit 8, the contents stored in the memory circuit 9 are given to an annunciator 6 through an output circuit 7. Accordingly, the reliability is improved, and the maintenance can be facilitated.

なっていた。In such conventional control devices, when a failure occurs such as when a switch element does not perform the specified operation in response to a step-up command, abnormal voltage or current in the switch element's output circuit (DC motor circuit), etc. is detected. For example, the output circuit of the switch element is turned off by turning off the advance command axis or by giving a separate output off command (not shown) to turn off the output of the control device and turning off the output of the switch element. is protected from abnormal voltage and machihara. Therefore, in the state after the protective operation,
Because the number of advance steps or the operating state of the switch elements at the time of failure is unknown, as mentioned above, in actual electric vehicles, there are a large number of switch elements and control steps, making it difficult to investigate the cause and take recovery measures. There was a drawback. Furthermore, since the output of the switch element is turned off after detecting abnormal voltage or current after it has risen, the reliability of the output circuit of the switch element is poor.

ッチ要素の制御装置。In a device in which the switch elements are sequentially operated to control the output, the first step is to input a stage advancement command for the switch elements.
an input circuit, a first output circuit that outputs an operation command to the switch element, a second input circuit that inputs a detection signal of the operation state of the switch element, a display that displays the switch element or a symbol representing the operation of the switch element; a second output circuit that outputs an operation command to the display; an eighth input circuit that inputs a predetermined inspection command when the sequential operation of the switch element fails; an input code of the first input circuit or the first output circuit; a second storage circuit capable of storing the number of steps of an instruction code to be commanded, an input code of the second input circuit, etc.; a command to output to the first output circuit in response to an input signal of the first input circuit; A code is commanded, and after a time that exceeds the sum of the operating times of the first output circuit and the switch element, the input code input to the second input circuit and the instruction code given to the first output circuit are compared and determined. If the judgment results do not match, the instruction code for stopping the output operation of the switch element is commanded to the first output circuit, the storage operation is performed to the first storage circuit, and the instruction code for the eighth input circuit is sent to the first output circuit. a second memory circuit that stores a program for reading out the memory code of the first memory circuit in accordance with an input code and instructing the second output circuit to output an instruction code; Second.
each of the eighth input circuits and the first. each of the second output circuits and the first. A control device for a switch element, comprising a control circuit that controls a second storage circuit according to a program in the second storage circuit.
